Adipose stromal cells (ASCs) serve as mesenchymal progenitors in white adipose tissue (WAT). Intercellular interactions involving Bicalutamide androgen receptor ASCs have remained obscure. By merging phage display engineering with fluorescence-activated cell sorting (FACS), we screened a combinatorial library for peptides that target mouse ASCs in vivo. We isolated peptide CSWKYWFGEC that specifically properties to ASCs, employed it as bait to purify the corresponding ASC surface receptor, and identified it like a previously unreported cleavage products of decorin (DCN) lacking the glycanation website (termed Delta DCN). We show that Delta DCN is differentially expressed onEphrin receptor ASC surface. Inside a display for Delta DCN-binding proteins, we recognized resistin, an adipokine for which the receptor has become unknown. Expression of Delta DCN in 3T3-L1 cells promoted proliferation and migration but suppressed lipid accumulation upon adipogenesis induction, which was resistin dependent. We conclude that Delta DCN serves as being a functional receptor of resistin in adipocyte progenitors and could regulate WAT growth.
